Why would ‘they’ “like to relate their aqueous situation with basic Buddha-Dhamma and the Centre”? Is it because ‘they’ are trying to make Truth An Add-On for the Ego?

A: No-one tries to MAKE TRUTH AN ADD-ON FOR THE EGO.

It is the phantom Egoic mind, the offspring of false identification with mind and body (remember Genesis: “they saw that they were naked”?). This it is that will grasp after anything it perceives as food for itself so that it can continue its phantom existence. Its relationship with the Real Self is a bit like that of a tapeworm with its host.
